If you wear eyeglasses, then you know how uncomfortable and troublesome a pair of crooked glasses can be. Here's what you can do to adjust your eyeglasses so that you can see properly again.
Gather the right tools. The tools you'll need to adjust your eye glasses will depend on the adjustments you need to make. In general, have available a Philips head screwdriver, a flat-head screwdriver, needle-nose pliers with a smooth inside (not serrated), Lock tight or other adhesive and a soft, non-abrasive cloth.
Consider the type of frame you have. Before you start making adjustments to your eyeglasses, you need to consider what type of frames you are wearing. They can be either plastic, metal, semi-rim, or rimless (also known as drill mount or rimless). If you have plastic frames, you cannot adjust these eyeglasses yourself (except for the arm or temple). Other repairs need to be done by a professional with the use of a hot box. Otherwise, the following instructions should help you adjust your eye glasses.
Adjust the arm's temple piece. When you are glasses are sitting crooked on your face, if you take them off you may notice that the temple arm has been twisted up or down. Take the them off, put them on a level surface upside down to confirm that they aren't balanced. Your glasses should always sit straight, so you'll need to adjust them using the following method.
On a full metal or semi-rimless frame, use your needle-nose pliers. Grip the frame and twist the temple upward very gently until you feel the frame moving. (On a drill mount frame, shift your grip to the drill mounts as you adjust your eyeglasses.) Check to see if your temple is level by placing your glasses upside down on a flat surface. Be careful not to snap any weld points by applying too much twisting force during this process.
If your glasses have a full plastic frame and one side is sitting higher than the other, you can only make adjustments at the screw hinge itself. Grasp the lens and frame with one hand and grasp the temple with your other hand. Gently bend the temple arm upward or downward slightly.
Adjust the earpiece. If your ear piece is uncomfortable, you can either straighten your frames outward to make the curve father toward the back. Or you can bring the curve inward to make it tighter or snugger. Again, consider the type of frame your have before you adjust your eyeglasses.
If the frames of your eyeglasses are full metal, semi-rimless or drill mount, use your hands and grab the earpiece. Twist it to adjust it inward or outward (depending on the adjustment that needs to be made.) Use you other hand to steady the temple arm of your eyeglasses as you adjust the earpiece of your eyeglasses.
Adjust the nose pads. On your eyeglasses, your nose pads determine how high your glasses will actually sit on your face, and where they sit on your nose in general. If the frames are too high, the pads are too close and need to be spread out. On the other hand, if your frames sit too low on your nose, the nose pads need to be adjusted inward to bring your glasses higher on your face. If you find that your glasses sit crooked on your face, this may also be a nose pad problem where one is off center.
If your glasses are entirely metal, grab the frame one lens firmly with one hand. On a semi-rimless or drill mount frame, shift your grip to the middle of your glasses, right above your nose pads. Use your other hand to gently adjust the nose pads inward or outward. The nose pads should sit balanced so that your eyeglasses so that sit level on your face.
You can make other repairs to your eyeglasses easily by adjusting screws with a screwdriver, or snapping lenses back into place. In all cases, use the least amount of force necessary when adjusting your eyeglasses to avoid breaking your glasses.
